Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a screen machine for sewage treatment. Background Art

[0002] The screen machine for sewage treatment, also known as the screen decontamination machine, is a solid-liquid separation equipment that can continuously remove impurities in the fluid. It is an indispensable special equipment in the production process of urban sewage treatment, water plants, power plant water inlets, textiles, food processing, papermaking, leather and other industries. It is a solid-liquid screening equipment commonly used in China;

[0003] When the screen machine for sewage treatment is in use, the driving device often drives the screen chain to rotate in the direction of the countercurrent through the sprocket. The screen chain salvages the floating objects and sediments in the sewage and lifts them out of the water. When the screen chain rotates to the top, the screen chain pours the sediments into the external debris hopper, and the dirt adhering to the outer surface of the screen chain needs to be cleaned by spraying cleaning water through the nozzle to ensure the subsequent screening effect;

[0004] During the use of the existing sewage treatment screen machine, although the screen chain can be cleaned by spraying cleaning water through the nozzle, the position of the nozzle is mostly fixed, resulting in limited coverage area of ​​the nozzle and certain cleaning dead angles, which affects the subsequent screening effect of the screen chain. Some sewage treatment screen machines use multiple groups of nozzles to clean the screen chain at the same time. Although this method increases the coverage area of ​​the nozzle and reduces the cleaning dead angle, it also makes the internal structure of the sewage treatment screen machine more complicated and the cost is relatively high. For this reason, we propose a sewage treatment screen machine. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a screen machine for sewage treatment. Through the cooperation of the rack plate and the one-third gear, the nozzle can be driven to perform longitudinal reciprocating motion, thereby increasing the cleaning area of ​​the nozzle, reducing the cleaning dead angle, further improving the cleaning effect of the screen chain, reducing the number of nozzles, having a simple structure and relatively low cost, and can effectively solve the problems in the background technology.

During the process of the grille machine for sewage treatment, open the water inlet gate. The flushing water enters the interior of the water inlet pipe 84 through the external pipe and finally sprays out through the nozzle 83, thereby flushing the stains adhered to the surface of the grille chain 5.
